Velocity of electromagnetic waves depends upon_and electric permittivity.
Correct answer: B. Magnetic permeability
- A. Longitude
- B. Magnetic permeability
- C. Electric field
- D. None of these
Explanation
In materials other than a vacuum, the velocity of electromagnetic waves indeed depends on both the electric permittivity and the magnetic permeability of that specific material. So, in a material medium, changes in both the magnetic permeability and the electric permittivity affect the propagation speed of electromagnetic waves.

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
